6:15-7:45: Supporting multiple device definitions – Chiu-Ki Chan

Designers and developers have been afraid of the variety of Android flavors for way too long. Android borrows a lot of concept from the web, and we can use the same techniques to cater to the different OS versions and form factors.

Be responsive. Forget about absolute coordinates. Embrace the relative, use resource folders to differentiate among screen sizes, much like CSS media queries.

Be progressive. Take advantage of the latest Android functionalities, but gracefully fall back to the basics when you are on older OS versions. Remember the days when not all browsers have javascript?

Best of all, you don’t need a huge team to do this. I run a one-person company, and I will show you how I applied these techniques to my apps Monkey Write and Heart Collage.

About Chiu-Ki Chan:

Chiu-Ki started writing mobile apps at Google, where she worked on Google Mobile Maps for Android. After a brief stint in web development at two startups, she is now back to her mobile roots with her own company for app development. Her apps include Monkey Write for learning Chinese writing and Heart Collage for snapping photos to stitch into a heart.

When she is not writing apps, she can be found travelling the world, sometimes sightseeing, sometimes dispensing Android tips on stage at various tech conferences.

6:15 : MEAN 2.0 Architecture by Scott Davis

2015 was a watershed year — new versions of HTML (HTML5), JavaScript (ECMAScript 6), and HTTP (HTTP/2) were all officially released. Frameworks, platforms, and libraries were quick to follow — Node 4.x, Polymer 1.x, Material Design, Web Components, and (of course) Angular 2 went into beta.
All of these new versions add up the most significant, coordinated changes to the web platform since the AJAX revolution of 2005.

In this presentation, Scott will talk about all of the core browser technologies you’ll need to be familiar with in order to be successful with the new MEAN 2.0 technology stack.

Scott Davis is the founder of ThirstyHead.com, a training and consulting company that specializes in leading-edge technology solutions like HTML 5, NoSQL, Groovy, and Grails. Scott is also the author/presenter of the O’Reilly video series “On the Road to Angular 2”

6:15-7:45: Introduction to Reactive – Daniel Hinojosa

Reactive is a the latest buzzword to consume our industry. This presentation distills and defines reactive systems, describe the difference between reactive architecture vs. reactive programming, describe common patterns, and demos the popular reactive JVM technologies like RXJava, and Akka.

Introduction to reactive gets in deep on a discussion of patterns: Source, Sink, Back Pressure, Reactive Pull/Push including a Light introduction to actors using Akka, ReactiveX using RXJava and Reactive Streams in RXJava and Akka. We also will showcase the differences between ReactiveX and Akka.

6:15-7:45: Building Java Applications on Cassandra – Tim Berglund

So you’re a JVM developer, you understand Cassandra’s architecture, and you’re on your way to knowing its data model well enough to build descriptive data models that perform well. What you need now is to know the Java Driver.

What seems like an inconsequential library that proxies your application’s queries to your Cassandra cluster is actually a sophisticated piece of code that solves a lot of problems for you that early Cassandra developers had to code by hand. Come to this session to see features you might be missing and examples of how to use the Java driver in real applications.

About Tim Berglund:

Tim is a teacher, author, and technology leader with DataStax, where he serves as the Director of Training. He can frequently be found speaking at conferences in the United States and all over the world. He is the co-presenter of various O’Reilly training videos on topics ranging from Git to Distributed Systems, and is the author of Gradle Beyond the Basics.

6:15-7:45: Git Internals – Jim Moore

Git is a fundamental rethinking of how source code management works. It has long since become the de-facto standard for open-source projects, and is rapidly displacing legacy systems in enterprises as well.

While it can be used like “traditional” source management systems, it can be a little clunky to do so because it’s designed to do so much more. Best of all, it’s able to do that by being much simpler than prior generations of source code management.

We’ll demystify git: it’s fundamentally some very basic computer science that allows it to be so flexible. I’ll show what’s going on with those funny looking revision numbers, interactive rebasing, editing the immutable history, hash-keys and block chains, one-sided merges, etc. It’ll then be painfully obvious how they work, enabling you to really take advantage of its power.

This isn’t a “This is how to work with git” but rather “This is how git works.” In other words, we’ll be talking less about the tool and more about the very cool computer science manifested by the tool.

About Jim Moore:

During decades of working at other Fortune 200 companies and startups, Jim Moore (https://keybase.io/jmoore) has designed and built several very large enterprise systems (including one spanning continents and another detecting terrorist threats). A heavy emphasis on automation and testing, especially using open-source, has been an integral part of that, leading him to be a committer-emeritus for the Apache Software Foundation and the Spring Framework. He has spoken at development conferences and active in several user groups, in addition to being a husband and daddy of three very cute little girls.

6:15-7:45: Agile, Not Fragile – Dr. Venkat Subramaniam

Agile adoption has gone through the roof. Almost every organization is now agile, in some form or fashion. However, a number of organizations are inflicted by “Agile by convenience” where they take on practices that are easy to adopt. Agile is not about what we do, but how we do it and what we get out of it. “Are we succeeding?” is the most important question to ask. How can we avoid the fragility that comes from the realities of the world we live in—complexities of projects, distributed teams, multi-team collaborations, organizational structures, market influences,…? In this presentation, award winning author, an agile practitioner and coach will discuss the practicalities of achieving agility and succeeding with meaningful agile practices. He will share about practices and approaches that are not necessarily easy, but those that are essential to success in development.

About Dr. Venkat Subramaniam:

Dr. Venkat Subramaniam is an award-winning author, founder of Agile Developer, Inc., and an instructional professor at the University of Houston. He has trained and mentored thousands of software developers in the US, Canada, Europe, and Asia, and is a regularly-invited speaker at several international conferences. Venkat helps his clients effectively apply and succeed with agile practices on their software projects. Venkat is a (co)author of multiple books, including the 2007 Jolt Productivity award winning book Practices of an Agile Developer. His latest book is Functional Programming in Java: Harnessing the Power of Java 8 Lambda Expressions. You can reach him by email at venkats@agiledeveloper.com or on twitter at @venkat_s.
